The sentinel lymph node (SLN) procedure is a feasible and accurate method for staging vulvar cancer. This technique correctly identified metastatic disease in lymph nodes, showing no false-negative results.

Area of Science:

  • Oncology
  • Surgical Pathology
  • Gynecologic Oncology

Background:

  • Vulvar cancer staging relies on accurate assessment of lymph node involvement.
  • The sentinel lymph node (SLN) procedure offers a minimally invasive approach to staging.

Purpose of the Study:

  • To evaluate the feasibility, efficacy, and accuracy of the SLN procedure in patients with early-stage vulvar cancer.
  • To determine the relationship between tumor location and SLN detection rates.

Main Methods:

  • Prospective data collection from 42 patients with clinical stages I-II vulvar cancer undergoing SLN detection followed by complete inguinofemoral lymphadenectomy.
  • Analysis of demographic, surgical, and pathologic data.

Main Results:

  • A 95% detection rate for at least one SLN per patient was achieved.
  • The SLN procedure accurately identified all metastatic lymph nodes, with no false-negative results.
  • Detection of bilateral SLNs was associated with tumors located closer to the midline.

Conclusions:

  • Sentinel lymph node dissection is a feasible and safe procedure for vulvar cancer.
  • Tumor proximity to the midline influences the ability to identify bilateral sentinel inguinal lymph nodes.
